Table 3

Integrated flux density computed by RAPTOR and BHOSS for the model described in Sect. 4.2.2, as well as the relative error, showing convergence of the output of the two codes.

Pixels	I_{230 GHz, RAPTOR}	I_{230 GHz, BHOSS}	ΔI∕I
128 × 128	2.39467	2.36903	1.07
256 × 256	2.39794	2.38237	0.65
512 × 512	2.39871	2.39133	0.31
1024 × 1024	2.39899	2.39553	0.14
2048 × 2048	2.39898	2.39777	0.050
4096 × 4096	2.39896	2.39881	0.0063

Notes. The last column reports the relative difference between the two codes, which is, Δ I∕I := (I_{230 GHz, RAPTOR} − I_{230 GHz, BHOSS})∕I_{230 GHz, RAPTOR}.
